BOTTLE-WASHING MACHINE.

Specification of Letters Patent.

Application filed November 1, 1916. Serial No. 128,813.

7 '0 all whom it may concern:

Be it known that I, JUAN BAENNINGER, a citizen of Argentine Republic, a resident of Quilmes, Buenos Aires, Argentina, have invented certain new and useful Improvements in Bottle-Washing Machines, of which the followin is a full, clear, and exact description, re erence being bad to the accompanying drawlng, forming a part of this specification.

My invention relates to improvements in bottle washing machines, one of the obJects being to provide an efiicient means for washing the inner faces of bottles. With this object in view, the machine preferably co nprises a tank or reservolr, a bottle carrier adapted to hold inverted bottles, and a vertically movable bottle washing dGVIGB 1ncluding nozzles adapted to be lnserted into the inverted bottles, said parts being so arranged that the water passing from the nozzles to the inverted bottles will drain into the reservoir. The nozzles are preferably arranged within the reservoir, and the bottles are preferably carried over the reservoir at points above the nozzles.

Another object is to produce a bottle washing machine having two bottle washing devices adapted to discharge water 1nto 1nverted bottles, reservoirs adapted to receive the water which drains from the inverted bottles, and means for forcing water from one of said reservoirs to one of the bottle washing devices so as to utilize this water in a primary washing operation. One of the bottle washing devices is supplied with fresh water which is utilized in the final washing or rinsing operation, and after being so used the water drains into the reservoir from which it is pumped to the other bottle washing device.

A further object is to produce a most efficient means for performing successive washing operations. To accomplish this the machine preferably includes a series of nozzles adapted to be inserted into the bottles, the latter being advanced step by step, from one nozzle to another, and the discharge ports of the different nozzles lie at angles to each other so that the water will be discharged at various points on each bottle during the successive washing operations.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawlngs wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

Figure I is a side elevation of a bottle washing machine embodying the features of my mventlon.

Fig. 11 is a transverse section of the machine.

Fig. III is a section taken approximately on the line III-III, Fig. II.

.Fig. IV is a diagrammatical plan view showing the arrangement of the discharge ports of the nozzles.

Fig. V is a fragmentary view showing the upper end of a nozzle.

The machine I have shown to illustrate the preferred form of my invention, com prises a large tank having side walls 1 and 2, end walls 3 and 4, a bottom wall 5, and a partition wall 6 dividing the tank into compartments A and B.

The bottle carrier comprises a pair of endless sprocket chains 6, arranged at the exterior of the tank, and fitted to idle sprocket wheels 7, 8 and 9 at the side walls of the tank. The sprocket chains are driven through the medium of drive wheels 10 fixed to a shaft 11. These sprocket chains travel through guideways G, located near the upper edge of the tank, each of said guideways being provided with side walls 12 and 13. In the structure I have shown the walls 13 are formed by the upper margins of the tank, and the walls 12 are formed by Z l)tll'.- secured to the side walls of the tank. A hood 14, arranged above the tank is provided with downturned flanges 1.3 having their lower margins arranged between the walls 13 of the chain guideways (i. Fig. ll. Angular brackets 16, secured to the hood 14, rest upon the walls 1:2 of the guideways G so as to constitute supports for the hood.

H designates bottle holders extending across the tank and secured to the sprocket chains 6 at the exterior of the tank. Each bottle holder comprises a series of bottle receiving pockets 17 secured to a channel bar 18, and angular arms 19 extending from the ends of the bar 18 and secured to the sprocket chains 6. 20 designates funnel shaped members (Fig. III) arranged imme- Patented July 3, 1917.

diately below the bottle receiving pockets 17 and adapted to receive the long nozzles 21.

The bottles are introduced into the bottle holders at a point X, (left side of Fig. I)

and discharged at the point X, at the right hand side of Fig. I. The bottle carrier is moved step by step by means of mechanism which will be presently described, and when the bottle carrier is at rest the nozzles 21 are inserted through funnel shaped members 20 and into the inverted bottles for the purpose of washing the inner faces of the bottles. Thereafter the nozzles 21 are withdrawn from the bottles to permit the bottle carrier to continue its intermittent movement. The inverted bottles are drained as they move toward the discharge point of the machine, and the water passing from the bottles flows into the compartments A and B.

The means for operating the bottle carrier comprises a power shaft 23, (Fig. I)

a pinion 24' secured to said power shaft, 9. gear wheel 25 meshing with said pinion 24, a pinion 26 secured to gear wheel 25, a gear wheel 27 meshing with pinion 26, a shaft 28 secured to gear wheel 27 and a crank arm 29 secured to said shaft 28. The crank arm 29 is shown in Figs. I and II. The mechanism just described is driven continuously to impart an intermittent movement to transmission devices which move the bottle carrier step by step. These transmission devices include a wheel W having a series of radial slots 30 adapted to receive the crank pin 29' on the crank 29, and also having a series ofarcuate faces 31 adapted to be engaged by the peripheral face of a disk 32 which is secured to the constantly rotating shaft 28.

'When the mechanism occupies the position shown by dotted lines in Fig. I, the crank pin 29'jis arranged in one of the radial slots 30, and a portion of the slotted wheel W is located directly opposite a recess 33 in the disk 32. When the crank pin 29 passes from the radial slot in the wheel W, the peripheral face of the disk 32 engages one ofthe arcuate faces of the wheel W, to prevent the latter from turning. It will be noted that the wheel W is driven intermittently by the constantly rotating crank arm 29, and that this intermittent movement is transmitted through ashaft 34 to a gear wheel 35 which meshes with a larger gear wheel 36, the latter being secured to the 5 shaft 11 which constitutes the drive shaft are fixed to brackets 42 which are fastened to the side walls of the tank. The water pipes 38 (Fig. III) are secured to cross heads 43, slidably fitted to vertical guide rods 41', the latter being fixed to brackets 42 which are secured to the side walls of the tank. Flexible water supply tubes 45 lead from the water pipes 39 to a manifold 46 secured to the tank wall 2. This manifold 46 is provided with three discharge ports to permit the discharge of water into the three flexible tubes 45, and it is provided with a single inlet port for the reception of a water supply pipe 47. The water flowing from the supply pipe 47 passes into the manifold 46, through the different flexible tubes 45, into the water pipes 39, and is discharged through the nozzles 21 that are secured to the pipes 39. The water pipes 38, located in the compartment or reservoir A, Fig. III, are connected to a manifold 46' by means of flexible tubes 45. 50 designates a fresh water supply pipe secured to the manifold 46'. The fresh water flowing from pipe 50 enters the manifold 46, flows through the flexible tubes 45', into the water pipes 38, and through the long nozzles 21 which communicates with said pipes 38.

There are three rows of nozzles 21 in the compartment or reservoir B and the bottles travel step by step, from one row of nozzles to another, so that each bottle is subjected tothree washing operations in passing over the compartment B. After being washed by the water flowing from the nozzles'in compartment B, the bottles are thoroughly cleansed by the clean water flowing from the nozzles 21 in compartment A. The fresh water flowing from the supply pipe 50 is v conducted to the nozzles 1n compartment A, so that the final-washing operation is effected by the clean water obtained directly from the main water supply pipe. The water discharged into the bottles at the upper ends of compartment A, flows into said compartment and is afterward used for the primary washing operation which takes place at the upper end of compartment B. Each of these compartments is provided with an overflow opening 52 and a discharge pipe 53 leading from said opening. Water is drawn from the compartment A through a pipe 54 leading to a pump 55 which discharges the water into the pipe 47 leading to the manifold 46. The pump 55 may be constructed in any suitable manner, and it is preferably operated continuously to draw water from the compartment A and to force said water through pipe 47 and manifold 46 to the bottle washing device in compartment B.

As previously pointed out, the horizontal water pipes 39 in compartment B are secured to cross heads 40, the latter being slidably fitted to the guide rods 41. The pipes 39 and cross heads 40 constitute a vertically movable carriage, adapted to be raised to insert nozzles 21 into the bottles, and adapted to be lowered to permit the bottle carrier to travel over the bottle washing device. The means for raising and lowering this carriage comprises a pair of arms 56 connected to the cross'heads 40 by links 57 These arms 56 are rigidly secured to a rock shaft 58 which extends across the compartment B. The arms 56 are provided with extensions 59 adapted to receive a counterweight 60 which balances the weight of the bottle washing device in compartment B. The bottle washing device in compartment A is raised and lowered through the medium of arms 56 secured to a rock shaft 58, and provided with extensions 59 which support a counterweight 60. The rock shafts 58 and 58 extend through a side wall of the tank, and they are operated through the medium of mechanism which is shown most clearly in Fig. I. This mechanism includes arms 61 fixed to the rock shafts 58 and 58, a bar 62 connecting said arms 61, and a pitman 63 connecting said bar 62 to a crank 64:. This crank 64 rotates continuously so as to oscillate the arms 61 and rock shafts 58 and 58', thereby raising and lowering the bottle washing devices.

From the foregoing it will be understood that each bottle is subjected to five successive washing operations. The bottles travel from one nozzle to another in the paths indicated by straight arrows in Fig. IV. Each nozzle has a central discharge port at its upper end and three radial discharge ports (Figs. IV and V). The radial discharge ports of each nozzle are preferably formed at an angle of 120 degrees to each other and all of the nozzles may be made exactly alike. It is important to note, however, that each bottle is subjected to the cleansing action of the water discharge from a series of nozzles, and that the discharge ports of each of these nozzles lie at angles to each other. For example, the center line of one of the dischargeports of each nozzle in the left hand row (Fig. IV) is parallel with the center line of the pipe 39. One of the discharge ports in each nozzle of the next adjacent row is at an angle of 24 degrees to the center line of pipe 39. Each nozzle in the next succeeding row has one of its discharge ports arranged at an angle of 48 degrees to pipe 39, one of the ports of each nozzle in the next row being at an angle of 72 degrees to the center line of pipe 38, and each nozzle in the last row is so arranged that one of its ports is at an angle of 96 degrees to the center line of pipe 38. By constructing and arranging the parts in this manner, each bottle is washed thoroughly at all points throughout its inner face. The water under pressure is discharged at various different points on the inner face of each bottle during the successive washing operations, with the result of removing all dirt or other foreign matter that has a tendency to adhere to the inner faces of the bottles.

I claim 1. In a bottle washing machine, a series of nozzles for performing successive washing operations, the discharge ports of the different nozzles being at angles to each other to provide for the discharge of water at various points on each bottle during the successive washing operations.

2. In a bottle washing machine, a series of nozzles for performing successive washing operations, and means for conducting bottles step by step from one nozzle to another, said nozzles being arranged within the bottles during the washing operations, and the discharge ports of the different nozzles being at angles to each other to provide for the discharge of water at various points on each bottle during the successive washing operations.

3. In a bottle washing machine, a series of nozzles for performing successive washing operations, each nozzle having a series of discharge ports formed at an angle to each other, each discharge port of each nozzle be ing at an angle to each discharge port of the other nozzles so as to provide for the discharge of water at various points on each bottle during the successive washing operations.

4. In a bottle washing machine, a bottle carrier adapted to receive rows of inverted bottles, rows of nozzles for performing successive washing operations, means for moving said bottle carrier step by step to carry the bottles from one row of nozzles to another, means for moving the rows of nozzles into and out of the bottles, the discharge ports of the nozzles of each row being at angles to the discharge ports of the nozzles of the other rows so as to. provide for the discharge of water at various points on the inner face of each bottle during the successive washing operations.
